Specification of Letters Patent.

Application filed Septeniber27,1913. Serial No. 792,150.

having pot carrying supports at right angles to each other, the said frame being mounted to rock through an arc of ninety degrees whereby one pot support will be shifted from a horizontal to a vertical position and the other shifted from a vertical to a horizontal position and a turn table on which said frame is mounted, whereby the frame may be turned so as to support either pot adjacent and parallel to the furnace so as to be heated by the latter, while the cylinder is being drawn from the glass in the pot on the horizontal table.

My invention further consists in a. furnace and a rocking frame mounted on a turntable and carrying twopots located end to end and at right angles, sothat a quarter turn of the frame will lower one pot to a vertical position and raise the other to a horizontal position, and a half turn of the turn table will reverse the position of the rocking frame relative to the furnace whereby both pots may be moved to position to be heated by the furnace.

My invention further consists in the de tails of construction as will he more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation of an apparatus em bodying my invention and Fig. 2 iso similar view of a modification of the same.

1 represents a circular track, and 2 is a turn table mounted on flanged Wheels 3, which latter rest on the track.

4 is a frame secured to the turn table and provided with bearings 5, in which the shaft 6 has a rocking movement' Rigidly secured to the shaft 6, are the arms 7 which carry the pot supporting tables 8. These two tables are located edge to edge and at right angles as shown, and each carries a pot 9, the construction being such that when one pot is in its horizontal position, which is its position when the glass is being drawn therefrom, the other will be in a vertical or drawing position, thus permitting the excess of glass to drain therefrom prior to its being turned to a horizontal position. A quarter I turn of the shaft (5 shifts the vertical pot 9 into a horizontal position, and the horizontal pot into a vertical position, and a half turn of the turn table 2, carries the vertical pot around one hundred and eighty degrees.

Secured to the shaft 6, is the worm gear 10, which is in mesh with the worm 11 on the armature shaft 12 of the motorl The conductor wires 14 leading to the motor are connected with a reversing switch member 15, carried by the turn-table 2 and which is CO11Stll?"teCl to make contact with a switch member 16 located at the side of the turn table. Upon starting the motor, the'worm 11,'aeting on worm gear 10, turns the shaft 6 and thus turns the frame 7 ma direction to carry the vertical table to a horizontal position and the horizontal table to a vertical position, the construction being such that the motor may be reversed, which is essential with the pot supports as herein shown.

Secured to the turn table 2 at its center,

is the shaft 17, which'is supported near its lower end in a bearing 18, and is provided at its lower end with a bevel gear 19,which meshes with a bevel pinion 20 on the armature shaft 21 of the motor 22. By energizing this motor, the turn table may be turned 011 its trackway 1, and carry with it the rocking frame carrying the two pots 9.

23 is a furnace preferably provided with a concave inner face, and with fuel burners i 24 which may be for oil or gas, the openings 2-5 through which the burner pipes pass, be-

ing larger than the burner pipes, so as to permit the free passage of air, which cornmingling with the oil or gas as the latter issues from the burner, produces an intense heat sufficient to melt the excess glass remaining in the pot. This furnace is so located relative to thepots carrying, frame that the vertical pot will rest close up to the furnace, and the glass remaining the-rein will be melted, and as it becomes fluid, drain from the pot thus leaving the latter clean and ready to receive another supply of melted glass.

In the operation of the'apparatus the horizontal pot is under the drawing apparatus and contains the supply of melted Q maa rze glass from which the cylinder is drawn, the other pot being in position adjacent the furnace so as to be heated thereby, and its eX- rcss glass melted and permitted to drain off. After the cylinder has been drawn from the horizontal pot, the frame carrying the pots is rocked through an arc of ninety degrees, and the turn table given a half turn, so as to bring the pot from which the cylinder was drawn into a position before the furnace. The sequence in which these acts occur is not important. The frame may rocked to change the position of the pots, after which the turn table may be turned to carry the vertical pot around to the furnace, but I prefer to first actuate the turn -table so as to carry the vertical pot away from the furnace and then rock the pots carrying frame, so that as the horizontal pct descends to a-vertical position, all fluid glass therein will drain off into the pit immediately in front of the furnace. if r The construction shown in Fig. 2 is identiwith that shown in Fig. 1, except as to 2 5 ithe gearing for actuating the rocking frame "and turn table. In Fig. 2 shaft 26 passes loosely through the turn table 2, and is pro- I vided at its lower end with a bevel gear 27 which meshes with the bevel gear 28 on the 3b armature shaft 29 of the motor 30. The upper end of shaft 26 'is provided with a gear 31 which meshes with a gear 32 on horizontal shaft 33. This shaft is journaled in a bearing 34 secured -=to the frame 4:, and is 35 provided at its opposite end with a gear 35 meshing with gear 36 fast on shaft 6.

NVith the construction shown, the rocking frame carrying the pots can only rock through a quarter circle, hence with the 40 construction shown in Fig. 2, if power he applied from motor 30 to shaft 26, in a direction to carry the vertical table downwardly, the shaft 35 cannot rotate, consequently the rotation of shaft 26, will operate through the locked shaft 35 to rotate the turn table and the parts thereon, and thus carry the vertical pot away from the furnace. If now the motor 30 be reversed, shaft 33 will be rotated in. a direction to turn gear 36 and rock the pots carryingframe a. quarter turn, thus carrying the vertical pot which has been heated and drained to a horizontal position, and the other pot to a vertical position. in frontof the furnace. It is of c ursef'-{cv-"dent thatthe shaft 26 otated in-a' direction to rock the pots carry blocked against further movement, and a 6 continued rotation in the same direction, will operateto turn the table 2, and the parts thereon. It is also evident that other changes in the construction and relative arrangement of parts may be resorted to with- 6 out departing from the spirit of my invenrocking frame on said turn table, two tah ,ing frame, after the lat er has made a quarter turn, it will become tion, hence I would have it understood that I do not confine myself to the exact construc-- tion shown but consider myself at liberty to make such changes as may come within. the scope of my invention.
